Vista’s IPv6 & IPv4 will flood Internet DNS servers?

I’m surprised Steve Gibson isn’t leading the charge on this one:

I can’t believe that Vista’s side-by-side IPv4 & IPv6 stacks would cause the entire Internet’s DNS infrastructure to fall to its knees in agony. Were this true, I gotta figure the whole lofty goal of converting the Internet as a whole to IPv6 is a doomed prospect.

To me, the addition of the IPv6 stack to Vista will create the most likely opportunity for smooth transition over to IPv6. If the DNS infrastructure – which must’ve anticipated IPv6 for years now – can’t handle a slow, gradual influx of Vista clients making queries and submitting update requests, then we’re all in a lot more trouble than people are letting on.
